From Concrete
to Oak
Stainless steel, concrete, oak barrels: each cuvée follows its own aging journey.
Raw Concrete
Thermal Inertia
Used for 80% of production. Thick walls absorb temperature variations, ensuring steady fermentation without stressing the yeast. A neutral material, concrete preserves the pure fruit expression.
French Oak
Micro-Oxygenation
Reserved for the Château, Esthète and Chartreuse cuvées. The wood's porosity allows slow oxygen exchange: tannins polymerize and gain suppleness. Oak contributes its aromatic compounds - vanilla, soft spices, toasted notes.
